[0037] Reference Figure 1-Figure 2 The utility model provides an embodiment: a cooling device for processing environmentally friendly plastic film, comprising a box body 1, an inlet is opened on the left side of the box body 1, and an outlet is opened on the right side of the box body 1, so that the environmentally friendly plastic film can pass through the box body 1. A base 2 is fixedly connected to the bottom of the right side of the box body 1, and the base 2 supports and fixes the support column 61 and the shell 64. A fan 3 is fixedly connected to the back of the box body 1, and the hot air in the box body 1 is discharged by starting the fan 3. A cooling air conditioner 4 is fixedly connected to the right side of the back of the inner wall of the box body 1, and the cooling air conditioner 4 is started to cool the environmentally friendly plastic film in the box body 1. An adjusting component 5 is provided on the inner wall of the box body 1, and the tension of the plastic film in the box body 1 is adjusted by adjusting the component 5, and the residence time of the plastic film in the box body 1 can be extended. A winding component 6 is provided on the top of the base 2, and the winding component 6 is convenient for winding the cooled environmentally friendly plastic film, and the winding roller 63 that has been wound is convenient for assembly, disassembly and replacement.

[0038] Reference Figure 1 and Figure 3The adjusting component 5 includes a tensioning roller 51, and the tensioning roller 51 is distributed in two groups. Through the two groups of tensioning rollers 51, the upper surface and the lower surface of the environmentally friendly plastic film are contacted respectively. The inner wall of the tensioning roller 51 is rotatably connected with a connecting shaft 52, and the connecting shaft 52 is distributed in two groups. Through the movement effect of the connecting shaft 52, the tensioning roller 51 is driven to move vertically. The outer wall of the connecting shaft 52 is fixedly connected with an L-shaped plate 54, and the L-shaped plate 54 is distributed in two groups. Through the movement effect of the L-shaped plate 54, the connecting shaft 52 is driven to move vertically. In order to move vertically, a hinged rod 55 is hinged on the right end of the front side of the L-shaped plate 54, and two groups of hinged rods 55 are provided. Through the movement of the hinged rod 55, the L-shaped plate 54 is driven to move vertically. A connecting rod 56 is hinged on the top end of the hinged rod 55, and two groups of connecting rods 56 are provided. Through the rotation effect of the connecting rod 56, the hinged rod 55 is driven to move. A rotating block 57 is fixedly connected to the top of the connecting rod 56. Through the rotation effect of the rotating block 57, the two groups of connecting rods 56 are driven to rotate at the same time.

[0039] Reference Figure 2 and Figure 4 The winding assembly 6 includes a support column 61, which supports and fixes the cylindrical shaft 66 and the second motor 62. The front of the support column 61 is fixedly connected to the second motor 62, and the output shaft of the second motor 62 is fixedly connected to the cylindrical shaft 66. By starting the second motor 62, the cylindrical shaft 66 is driven to rotate, and the outer periphery of the cylindrical shaft 66 is connected with a winding roller 63. Through the rotation effect of the winding roller 63, the cooled environmentally friendly plastic film is wound up. The top rear end of the base 2 is fixedly connected to a shell 64, and the inner wall of the shell 64 is slidably connected to a movable column 65. Through the sliding effect of the movable column 65, the height of the movable column 65 is adjusted, so that the movable column 65 contacts the bottom of the cylindrical shaft 66, thereby supporting the cylindrical shaft 66.

[0040] Reference Figure 1 and Figure 3 A first motor 59 is fixedly connected to the front of the box body 1, and the fixing effect of the first motor 59 prevents the first motor 59 from falling off. The output shaft of the first motor 59 is fixedly connected to the rotating shaft 58. By starting the first motor 59, the rotating shaft 58 is driven to rotate. A slider 53 is fixedly connected to the front of the connecting shaft 52, and the fixing effect of the slider 53 prevents the slider 53 from falling off. A sliding groove is opened on the inner wall of the box body 1, and the outer wall of the slider 53 is slidably connected to the inner wall of the sliding groove. The sliding effect of the slider 53 and the sliding groove guides the connecting shaft 52 to prevent the connecting shaft 52 from deviating when moving.

[0041] Reference Figure 2 and Figure 5The bottom of the support column 61 is fixedly connected to the top front end of the base 2. The fixing effect of the support column 61 prevents the support column 61 from falling off. The inner wall of the bottom end of the right side of the movable column 65 is elastically connected with a wedge block 68 through a spring 69. Through the elastic force of the spring 69, the wedge block 68 always maintains a card connection effect with the card slot when not affected by external force, thereby limiting the movable column 65. A card slot is opened on the right side of the shell 64.

[0042] Reference Figure 4 The outer periphery of the cylindrical shaft 66 is rotatably connected to the inner wall of the support column 61. The rotation effect of the cylindrical shaft 66 drives the limit block 67 to rotate. The top of the cylindrical shaft 66 is fixedly connected to the limit block 67. The fixing effect of the limit block 67 prevents the limit block 67 from falling off. The outer periphery of the limit block 67 is clamped with the inner wall of the winding roller 63. Due to the clamping effect of the limit block 67 and the winding roller 63, when the limit block 67 rotates, it drives the winding roller 63 to rotate.

[0043] Reference Figure 2 The outer periphery of the rotating shaft 58 is rotatably connected to the front inner wall of the box body 1, and the rotating block 57 is driven to rotate through the rotation effect of the rotating shaft 58. The rear end of the rotating shaft 58 is fixedly connected to the front side of the rotating block 57, and the fixing effect of the rotating block 57 prevents the rotating block 57 from falling off.

[0044] Reference Figure 5 The wedge block 68 is fixedly connected to the inner wall of the right bottom end of the movable column 65, and the other end of the spring 69 is fixedly connected to the outer wall of the wedge block 68. The fixing effect of the spring 69 keeps the wedge block 68 fixed to prevent the wedge block 68 from falling off. The outer wall of the wedge block 68 is slidably connected to the inner wall of the right bottom end of the movable column 65. The sliding effect of the wedge block 68 makes the wedge block 68 engage or release the engagement with the slot. The outer wall of the wedge block 68 is engaged with the inner wall of the slot. The engagement effect of the wedge block 68 and the slot makes the shell 64 limit the movable column 65. One side of the wedge block 68 is an arc surface, and the other side of the wedge block 68 is a straight surface. By setting the wedge block 68 to have an arc surface on one side and a straight surface on the other side, when the movable column 65 slides upward, the shell 64 can squeeze the arc surface of the wedge block 68, so that the wedge block 68 squeezes the spring 69 to contract.

[0045] Working principle: When the staff needs to cool the environmentally friendly plastic film, the staff will pass one end of the environmentally friendly plastic film from the left entrance of the box body 1 through the two sets of tensioning rollers 51 set on the inner wall of the box body 1, and pass through the right outlet of the box body 1, and curl it on the winding roller 63. The staff will start the cooling air conditioner 4, the fan 3 and the second motor 62. The environmentally friendly plastic film in the box body 1 is cooled by the cooling air conditioner 4, the hot air in the box body 1 is discharged by the fan 3, and the cylindrical shaft 66 is driven to rotate by the second motor 62, so that the limit block 67 drives the winding roller 63 to rotate, and the cooled environmentally friendly plastic film is wound up.

[0046] When the staff needs to adjust the time that the environmentally friendly plastic film stays in the box body 1 or needs to tension the environmentally friendly plastic film, the staff starts the first motor 59, and the first motor 59 drives the rotating shaft 58 to rotate, so that the rotating block 57 drives the two groups of connecting rods 56 to rotate, and the two groups of connecting rods 56 drive the two groups of hinged rods 55 to rotate respectively, and the two groups of L-shaped plates 54 are driven by the two groups of hinged rods 55 to move vertically, and the two groups of connecting shafts 52 are driven by the two groups of L-shaped plates 54 to move vertically, thereby driving the two groups of tensioning rollers 51 to move vertically, so that the two groups of tensioning rollers 51 squeeze the upper surface and the lower surface of the environmentally friendly plastic film respectively, thereby adjusting the time that the environmentally friendly plastic film stays in the box body 1 and the tensioning force of the environmentally friendly plastic film.

[0047] When the winding roller 63 has been wound up, the staff member presses the wedge block 68 so that the wedge block 68 releases the clamping effect on the slot and releases the limiting effect on the movable column 65. The movable column 65 slides downward under the influence of its own gravity to release the contact effect with the cylindrical shaft 66, making it convenient for the staff member to remove the wound winding roller 63 from the cylindrical shaft 66 and insert the replaced winding roller 63 onto the cylindrical shaft 66 so that the limiting block 67 is clamped with the inner wall of the replaced winding roller 63 and the movable column 65 is slid upward so that the movable column 65 contacts the bottom of the cylindrical shaft 66 to support the cylindrical shaft 66. At the same time, the wedge block 68 is clamped with the inner wall of the slot under the elastic force of the spring 69 and limits the movable column 65 so that the movable column 65 remains fixed, thereby completing the replacement of the winding roller 63.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
